The abdominal wall hernia in cirrhotic patients: A historical challenge

2018

Abstract Background The incidence rate of abdominal wall hernia is 20–40% in cirrhotic patients. A surgical approach was originally performed only if complication signs and symptoms occurred. Several recent studies have demonstrated the usefulness of elective surgery. During recent decades, the indications for surgical timing have changed. Methods Cirrhotic patients with abdominal hernia who underwent surgical operation for abdominal wall hernia repair at the Policlinico “Paolo Giaccone” at Palermo University Hospital between January 2010 and September 2016 were identified in a prospective database, and the data collected were retrospectively reviewed; patients’ medical and surgical records…

The abdominal wall incisional hernia repair in cirrhotic patients

2018

BACKGROUND: The incidence of abdominal wall hernia in cirrhotic patients with ascites is between 20 and 40%. Controversies regarding the treatment modality and surgical timing of abdominal wall incisional hernia repair in cirrhotic patients remain. The study proposed wants to analyze the abdominal incisional hernia repair in cirrhotic patients with ascites performed in a single center to determine post-operative morbidity, mortality and complication rate. PATIENTS AND METHODS: Cirrhotic patients with abdominal incisional hernia that underwent surgical operation for abdominal wall hernia repair at the "Policlinico Paolo Giaccone" at Palermo University Hospital between January 2015 and Decemb…

Iterative approach to the exponential representation of the time–displacement operator

2005

An iterative method due to Voslamber is reconsidered. It provides successive approximations for the logarithm of the time–displacement operator in quantum mechanics. The procedure may be interpreted, a posteriori, as an infinite re-summation of terms in the so-called Magnus expansion. A recursive generator for higher terms is obtained. From two illustrative examples, a detailed comparative study is carried out between the results of the iterative method and those of the Magnus expansion.

Ferrocene-quinoxaline Y-shaped chromophores as fascinating second-order NLO building blocks for long lasting highly active SHG polymeric films

2016

The first example of a Y-shaped ferrocene quinoxaline derivative with a surprisingly high and stable second harmonic generation (SHG) response in composite polymeric films is reported. The interesting quadratic hyperpolarizability values of different substituted Y-shaped chromophores are also investigated in solution by the EFISH technique.

Morphological and Postural Changes in the Foot during Pregnancy and Puerperium: A Longitudinal Study

2021

The aim of this study is to observe the morphological and postural changes to the foot that take place during pregnancy and the puerperium. Method: In this descriptive, observational, longitudinal study, we analysed 23 pregnant women, with particular attention to morphological and postural aspects of the foot, at three time points during and after pregnancy: in weeks 9–13 of gestation, weeks 32–35 of gestation and weeks 4–6 after delivery. The parameters considered were changes in foot length, the Foot Posture Index (FPI) and the Hernández Corvo Index, which were analysed using a pedigraph and taking into account the Body Mass Index (BMI). The same procedure was conducted in each review. Re…

Most studies have treated grandiose narcissism as a unidimensional construct and investigated its associations in cross-sectional convenience samples. The present research systematically addresses these limitations by investigating the associations of agentic and antagonistic aspects of narcissism in the interpersonal, intrapersonal, and institutional domains, cross-sectionally and longitudinally in a population-representative sample. We used data (N = 1,526) from the representative, longitudinal German Socio-economic Panel study innovation sample (SOEP-IS). Both pre-registered and exploratory research questions regarding interpersonal, intrapersonal, and institutional outcomes of agentic a…

Phytopathogenic Bacteria Associated with Bacterioses of Common Oak (Quercus robur L.) in Ukraine

2022

Studying the biological characteristics of the causative agents of bacteriosis of the common oak (Quercus robur L.) (to highlight the links between the key factors of pathogenesis and bacterial groups) is a new and relevant area of research. This work aims to identify the species composition of phytopathogenic bacteria associated with common oak bacteriosis and to study the morphological, cultural, and biochemical properties of pathogens. To establish the general phytosanitary state of the surveyed stands, classical forest inventory and phytopathological (visual on based on typical symptoms of the disease and macroscopic) methods were used. The properties of isolated bacteria were studied u…

Axiomatics and construction of the central place system

1987

The construction of the loschian landscape is a basic element in the Theory of Economic Regions. It is based on an hexagonal lattice and loschian numbers having properties used by DACEY (10,11,12,13) and MARSHALL (16,17,18,19,20). In fact, the former has not tested his model. In this paper our purpose is to prove that DACEY failed to build mathematically the Central Place System, and to propose a new method of construction of the loschian landscape.

Heat shock protein 60 autoimmunity and early lipid lesions in cholesterol-fed C57BL/6JBom mice during Chlamydia pneumoniae infection

2004

Chronic Chlamydia pneumoniae infection and autoimmunity to heat shock protein 60 (Hsp60) have both been documented to be associated with atherosclerosis. Herein, we studied the effects of C. pneumoniae infection and a diet with a low-cholesterol supplement on the development of autoantibodies to mouse Hsp60 and early lipid lesions in the aortic valve of C57BL/6JBom mice. In addition, pulmonary infection was investigated. C57BL/6JBom mice were given one to three C. pneumoniae inoculations and fed either a regular diet or a diet enriched with 0.2% cholesterol. Autoantibody responses against mouse Hsp60 developed in both diet groups when the mice were infected with C. pneumoniae and in uninfec…

Upon oxidative stress, the antiapoptotic Hsp60/procaspase-3 complex persists in mucoepidermoid carcinoma cells.

2008

Hsp60, a mitochondrial chaperonin highly conserved during evolution, has been found elevated in the cytosol of cancer cells, both in vivo and in vitro, but its role in determining apoptosis during oxidative stress (OS) has not yet been fully elucidated. The aim of the present work was to study the effects of OS on Hsp60 levels and its interactions with procaspase- 3 (p-C3) and p53 in tumor cells. NCI-H292 (mucoepidermoid carcinoma) cells were exposed to various concentrations of hydrogen peroxide (H2O2) for 24 hours. Cell viability was determined by Trypan blue and MTT assays. DNA damage was assessed by the Comet assay, and apoptosis was measured by the AnnexinV cytofluorimetric test. Expos…
